Soap bubbles professionals Saskia Marges and Jeroen Maatman from Bubblusion came to Leiden. For the series The Last Waltz they created special smoke bubbles. For the series Nocturnes they made a.o. ‘clustered’ shapes.
In The Last Waltz one session was filmed simultaneously from three different points of view. This resulted in three testimonies of one event.
In Nocturnes two films were shot in the former boiler room, one after the other. The other was shot on the fifth floor of the same building.
